33kV tension insulators are replaced by linemen working in Ceylon Electricity Board, at Kurunegala, Sri Lanka using insulator cradle and hot-sticks without interrupting power.
The method shown in the video is called Hot Stick method introduced in US in early 1910s with wooden sticks. Since this is live 33 kV potential, class 04 protection gloves with over gloves are normally required. However usage of Hotstick while keeping minimum safety distance from the live parts eliminates the requirement for bulky and difficult to handle insulated gloves. Therefore gloves are not used.
